I looked on the axminster site and could not find them, so i gave them a call. The tech support guy new the part number by heart, I ordered them on the web site about 3:30 on thursday and they arrived yesterday. You cant fault axminster for service.
The screws though are different from kreg ones, there is a slight radius at the top of the shank under the head and they are slightly bigger screws No7 rather than No6. Not sure if this makes any difference but i will find out tomorrow
